Inomax is primarily used to treat hypoxic respiratory failure associated with persistent pulmonary hypertension of the newborn (PPHN), a condition where blood flow through the lungs is restricted, causing low oxygen levels in newborns.
Inomax delivers nitric oxide gas directly to the lungs via inhalation. Nitric oxide activates guanylate cyclase in pulmonary vascular smooth muscle cells, leading to smooth muscle relaxation, vasodilation of pulmonary blood vessels, and improved blood flow and oxygenation.
Inomax is a prescription-only medication administered only in hospital settings with appropriate monitoring capabilities. It is specifically indicated for term and near-term neonates. Treatment requires specialized equipment and trained personnel. Patients should be monitored for potential rebound pulmonary hypertension if the medication is stopped abruptly.
